[Tinyos-help] [SPAM: 4.000] HplMsp430UsartInterrupts problems

[Allan McInnes]

The error you are seeing is a problem with mspgcc, not with Jan's  
code. You can find a discussion of the bug and suggestions for a  
bugfix at https://www.millennium.berkeley.edu/pipermail/tinyos-help/2007-August/027578.html

Cheers,
Allan
